Properties of Argon Gas Atomized Ti-43Al-9V-Y Alloy Powders

Abstract:

The properties of Ti-43Al-9V-Y alloy powders, which were produced by cold crucible melting and argon gas atomization, were investigated. The results showed that the size of the powders was normal distribution in a range of 10-210μm. The powders possessed a near perfectly spherical shape. The microstructure of the powders was composed of dendritic and cellular crystal grains, and the dendritic crystal grains decreased in finer particles. The X-ray diffraction result indicated that there were two main phases, α2 and B2 in the powders, and the amount of B2 phase increased as the particle size decreased. In addition, the oxygen and nitrogen contents were below 1000ppm and around 140ppm, respectively.
